ABSTRACT:
A transmission (1) for distributing a drive torque to at least two output shafts (7, 8) which has at least two planetary gear sets (2, 3) with at least three shafts wherein each shaft (4, 5) of a planetary gear set (2, 3) is connected with one input shaft (6). Besides, each shaft of a planetary gear set (2, 3) constitutes one of the output shafts (7, 8) and at least one other shaft (9or10) of a planetary gear set (2or3) is operatively connected with one shaft (10or9) of one other planetary gear set (3or2). A torque of a shaft (9or10) dependent on operating state can be supported according to an operating state of the respective other shaft (10or9) via an operative connection (11) therewith in a manner such that when a rotational speed difference occurs between the output shafts (7, 8) a torque that changes the rotational speed difference abuts via the operative connection (11) on the planetary gear sets (2, 3).
